The feature of the sun that extends into the corona but is anchored in the photosphere is called a "Prominence." Prominences are large, bright, gaseous loops or arches of plasma that rise above the sun's surface, projecting into the corona. They are visible during solar eclipses or when observed using specialized solar telescopes. These structures are anchored to the photosphere, which is the visible surface of the sun, by strong magnetic fields. Prominences are relatively stable and can last for days or even weeks, though some may erupt and release solar material in events known as solar flares or coronal mass ejections (CMEs).
I hope this helped!
